Rotatable Spool For Winding Cords or Hoses |
摘要 |
A rotatable spool includes a frame with a central rod and a hollow cylinder that is rotatable about the central rod. The cylinder includes an inscribed helical thread that is formed along the length of the cylinder and a central axis parallel with the central rod. The operator is disposed around a portion of the cylinder and includes a projection engaged with the helical thread such that linear movement of the operator causes the cylinder to rotate about its central axis. A reel is rotatably mounted on the frame and a clutch selectively couples the cylinder and the reel when the operator is depressed toward the frame.
